Having a hard time finding out just where these things seemed to have
all but disappeared.
Listing tables in one of my tablespaces I have the combinations of:
Pct_Free Pct_Used
Null null
10 null
10 40
It seems I can SET pct_free, but while it tells me it will set pct_used,
the select always comes up null.
Now I assume that this has to do with auto management, but where are the
rules and if for some reason we needed to tweak them, how would we go
about doing that.
We converted databases and used import/export to move them to a new box.
On the old box it was mostly 10/40, but on the new box we are finding
10/null. The user is claiming that it is much slower all because we
don't have the 40 in pct_used. I bet it's been 8 years since I played
with the setting and found the "opportunity" listed above. I would think
the auto management would take care of this for us.
Is there a good write up on it some place? Haven't found much other than
"how to set" and that doesn't seem to be working. Database is 10.2.0.3
on HP/UX.
